[QUOTE="Steerpike, post: 591846, member: 807"] You need a seriously heavy current to actually burn a cable's insulation. It is worse if the cable is coiled up. A 100m of ordinary cheap white ripcord makes a good dummy load for testing an amplifier, and I have done exactly that. 250W of audio, directly into the cable, no other load or sink, and the cable got very slighlty warm. The big 'worry' about small gauge cables (i.e., big SWG number, but thin wire) is that they add more resistance in series with the loudspeaker, and devolop a bigger voltage drop along their length. My scenario above shows that 100m of thinnish cable is equivalent to the loudspeaker impedance itself, so you'd lose 50% of the power in the cable itself. That's only 3dB though, so you'd barely notice the level difference. However, things like damping will be affected. [/QUOTE]
